It'd be a disaster. Lets face it. NFL in the UK, is a novelty, and I actually think it's wearing a little thin. The novel idea of any NFL, isn't a sell any more. This year, they got super fortunate that Eagles were picked before winning the Superbowl. But most lineups aren't great anymore and i think the sell of tickets is harder. They are trying to push the Jags on people, which is great, but likewise, it's a hard task.
London is what? 200miles from Liverpool. I can't really back the London Jags every week can i? Beside that, I've supported the Jets for 20 years, and i'm sure i'm not the only one, who won't be changing teams in a hurry, infact i categorically won't. The novelty will last what? 2-3 years. People come from all over the country, but can't they realistically do it 8+ times a year to support them? Especially when some games won't be finishing til potentially 9pm with work the next day. It can't work, it shouldn't be a thing, but it will be.
